This invention relates generally to mixing machines in which the liquidcontents of closed bottles or the like containers, is agitated andmixed, and particularly to a ma- 6 chine of this type which is to beplaced in the line of gravity conveyors, and handles'cases of bottles orcontainers, fed into the machine by a' conveyor, and more specificallyto a ma chine of thistype which is adapted to agitate and mix the liquidcontents of the said containers by an operation of rotating the machineabout a horizontal axis. T

It is an object of this invention toprovide a machine'of this type whichis readily placeable within and cooperable with a line of gravityconveyor, so that the loading and the unloading of the machine ispractically automatic, means being provided for securely retaining thecases of bottles or the like during therotation of the machine, andproviding means for holding the cases of bottles or the like on themeeting end of the conveyor, during the rotating operation. B It is alsoan object of this invention to .provide a device of the characterdescribed, which comprises new and novel features, which results in asuperior and more efiicient results, and which is simple andsatisfactory in op eration, which consists of few and simple andefficiently coordinated parts, and which is capable of being cheaply andquickly manufactured and installed.

These and other objects of the invention, its nature, its compositionand arrangement and combination of parts will be readily understood byany one acquainted with the art to which this invention relates uponconsulting the following descriptions of the drawings, inewhich:

Figure 1 is a general side elevational View J anychange or changes maybe made inmaterial, structure or arrangement of parts, consistent withthe spirit and scope of the invention. i

Referring in detail to the drawings, it will '1 be. seen'that the deviceconsists especially of a frame 5 consisting of fiat bars and channelirons suitably riveted or otherwise fastened together to providevertical corner members of an extension of one of the stub-shafts 12 isa hand Wheel 14. It is obvious that with the arrangement stated, turningthe handle wheel 14 will result in rotatingthe frame 5 on the axis ofthe stub-shafts 12., A section of a conveyor roller generally-designatedat 15 is placed upon a bottom member16 of the frame soas to facilitateloading and unload ing of the cases ofbottles or containers.

In Figure 1 the sections of gravity conveyors-are designated'15a and15b. The cases are. conveyed from the conveyor section 15a on to theconveyor section 15 secured in the mixer frame, and after mixing, thecases are discharged from the mixer frame on to the conveyorsection15b,

At the end of the conveyor section 15a is provided stop means forpreventing the cases thereon from leaving the end of said conveyorsection 15a. This stop means consists of'a pair of spring projected pins17 slidably 90. mounted in a block 18 secured across the end p of theconveyor section 15a. They'are re-' tracted by a foot treadle 19connected witha leverIQOWhich is pivoted on the far side of the conveyorsection, and the lower ends of the pins 17 have a link connected withthe lever- 20. The lever20 is normally held raised by a spring 20a 7for" normally maintaining the said stop pins 17 in upwardlyprojectedcase retaining position, for preventing the acci- 9 dental movement ofthe cases of bottles or the like from the end of the conveyor section,thus preventing accidental interference with the loading or unloading orrotation of the mixer.

On one side of and extending longitudinally of the frame is a bar 22suitably secured to the frame, on each end of which is an arm 21. Thesearms are adapted to be projected in the position indicated in Figure 3,for engagement against the outer sides of the cases or the like, toprevent the displacement of a case from the f 'ame in the longitudinaldirection during the rotation of the frame. Each arm 21 has an extension23 to which is connected a spring, latch mechanism 24 which is adaptedto engage the under edge of one of the upper side members 7 of the frame5 to maintain the arm 21 in firmly projected position during therotation of the frame.

To hold the cases against vertical displacement there is provided anadjustable follower 25 which is mounted in the upper portion of theframe, and is brought to bear firmly on the top of the cases. Forretracting the follower durin the loading operation, springs 2 areprovided coacting with rods QG-arising from the upper side of thefollower. For finally compressing the follower 25 3 against the topofthe cases there is provided a cam arrangement consisting of the lever 28and the arms 29 provided with the rollers 30, the lever andarms beingconnected to a shaft 32,.rotatably supported at the top of the frame sothat when the lever 28 is moved, the shaft 32-willflbe rockedto move thearms 21 into holding or releasi-n g position. Means generally designated33 and 84 are provided for re leasably retaining the lever 28 and hencethe cams in adjusted tightened position.

It is obvious that some means must be providedffor retaining th-e mixingframe against oscillation or partial rotation during the loading andunloading operations, and such a structure is provided and pivoted instandards 35, and consisting of a bar 36 running longitudinally underone side of the frame, and rotated'by a lever 37' attached to one end.Mounted for rotation with the bar 36 are detents 38 for engaging thebottom edge of lower 25 israised out of position, the conveyor, becomeoperative once again, and the cases may be uninterruptedly conveyed fromthe conveyor section 15a across and upon the conveyor section 15 mountedin the frame, and then to the conveyor section 15?), thus 7 providingfor automatic loading and unloadtion and requiring little labor forhandling and little additional expense for its operation, and which issimple and easy to maintain, and is cheap to manufacture.

What-is claimed is.: 1. A device of the class described comprisinga'frame supported for rocking movement and adaptedto hold a case ofbottled goods, a follower carried by the top of the frame for engagingthe top of the case, spring means for normally holding the follower inraised position, a shaft journalled in the top of the frame, armsattached to the shaft and havmg rollers at their lower ends engaging thefollower, when the shaft is moved to a position with the arms dependingtherefrom, and a hand lever connected with the shaft for rocking thesame. 2. A'device of the class described comprismg a frame supported forrocking'movement and adapted tohol'd a case of bottled goods, a followercarried by the top of the frame for engaging the top of the case, springmeans for normally holding the follower in raised position, a shaftjournalled in the top of the frame, arms attached to the shaft andhaving rollers at their lower ends engaging the follower, when the shaftis moved to a position with the arms depending therefrom, a hand leverconnected with the shaft for rocking the same, a shaft journaled in oneside of the frame, an arm fastened to the shaft each end thereof andintermediate the ends of the arms, oneend of the arm being adapted toengage a side of the case, and latch means at the other .end of each armfor engaging a parto'fthe frame to hold the arms in holding position. i

In testimony whereof I afiix my signature.
